About this study
Official title: This is an Open, Single-arm, Clinical Study to Evaluate the Efficacy and Safety of Anti-CD7/CD5 CAR-T Cells in the Treatment of Relapsed or Refractory T-cell Acute Lymphoblastic Leukemia (T-ALL), ETP-ALL, and Lymphoblastic Lymphoma (TLBL).
Chimeric antigen receptor (CAR)-modified T cells targeted against CD19 have demonstrated unprecedented successes in treating patients with hematopoietic and lymphoid malignancies. Besides CD19, many other molecules such as CD22, CD30,BCMA,CD123, etc. may be the potential to develop the corresponding CAR-T cells to treat patients whose tumors express those markers. In this study, investigators will evaluate the safety and efficacy of Sequential CAR-T Cells Targeting CD5/CD7 in patients with patients with relapsed or refractory T-ALL/LBL/ETP-ALL. The primary goal is safety assessment including cytokine storm response and any other adverse effects. In addition, disease status after treatment will also be evaluated.
Read the detailed description
Acute lymphoblast leukemia (T-ALL) is a neoplastic lymphoid leukemia characterized by the proliferation of immature precursor T cells. The combined chemotherapy has significantly improved the prognosis of T-acute lymphoblast leukemia/lymphoma. However, once the disease appears to be relapsed/refractory, there are limited treatment options, and the overall prognosis is extremely poor. Therefore, exploring safe and effective treatments is a critical unmet medical need. The patients will receive Sequential CAR-T Cells Targeting CD5/CD7 to examine the safety and, possibly the efficacy of CD5 CAR T-Cells in CD5+ CD7+ relapsed or refractory acute leukemia.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CD5/CD7 CAR-TBiological
Also called EB-BH2026
The intervention in this clinical trial involves a novel approach using CD5/CD7 Chimeric Antigen Receptor T (CAR T) cells combined with chemotherapy. The goal is to assess safety and efficacy in patients with specific hematologic malignancies.
Treatment Regimen:
Patients in the trial will undergo the following regimen:
Fludarabine Phosphate (Days -4 to -2): IV administration of fludarabine phosphate over 30 minutes on days -4 to -2. It's part of the preparatory regimen to enhance the body's response to CAR T-cell therapy.
Cyclophosphamide (Day -2): IV cyclophosphamide over 60 minutes on day -2.
CD5/CD7 Chimeric Antigen Receptor T Cells (Day 0): IV administration of investigational therapy, CD5/CD7 CAR T cells, over 10-20 minutes on day 0.
Additional Doses: Eligible patients responding well to the initial CD5/CD7 CAR-T cell infusion without unacceptable side effects and sufficient CAR-T cell availability may receive 2 or 3 additional doses.
| Study group | Role | What they receive |
|---|---|---|
| Sequential CAR-T Cells Targeting (CD5/CD7 CAR T cells, chemotherapy) | Experimental | Patients will be administered fludarabine phosphate intravenously (IV) over a 30-minute period on days -4 to -2. Additionally, cyclophosphamide will be administered intravenously (IV) over 60 minutes on day -2. Subsequently, patients will receive CD5/CD7 CAR T cells intravenously (IV) over a duration of 10-20 minutes on day 0. Patients who exhibit positive responses to the initial dose of CD5/CD7 CAR T cells, do not experience unacceptable side effects, and have a sufficient quantity of cells available may be eligible to receive 2 or 3 additional doses of CD5/CD7 CAR T cells. Receives: Biological: CD5/CD7 CAR-T |
What is being measured
The primary outcome is the main question the study is designed to answer.
The number and incidence of adverse events after CD7/CD5 CAR infusion.
Evaluation of all possible adverse reactions, including the number, incidence, and severity of symptoms such as cytokine release syndromes and neurotoxicity within 3 months after CAR-T infusion
Measured: 28 days
Disease response to CD7/CD5 CAR T cells
The disease response to CD7/CD5 CAR T cells is evaluated by bone marrow biopsy and aspirate within 1 year after CAR infusion. The proportion of subjects receiving CD7/CD5 CAR T infusion to 1) morphological remission (blasts <5%): 2) flow cytometry analysis was blast negative, and 3) molecular biological remission (if applicable).
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing CD5/CD7 CAR-T in people with T Cell Lymphoma and T Cell Leukemia, run by Essen Biotech at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 12 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rhoda M Smith, Phd (+12077706670, clinical-trials@essen-biotech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number and incidence of adverse events after CD7/CD5 CAR infusion. (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Nov 2024.
